The Jaguars finished the season with just two wins, losing 14 games and scoring more than 20 points on just four occasions. They also had the third-worst defense in the NFL, allowing 380.5 yards and 27.8 points per game.
Given the state of their team, its doubtful that Tebow would improve the Jaguars by much. He didn't develop at all this season and it's not like he was that great in the first place.
Sure, he led the Denver Broncos to a playoff win last season. But he was so unimpressive in practice this year that he couldn't even replace the awful Mark Sanchez. Even Dicks' Sporting Goods benched Tebow this season.
What Tebow would do, though, is improve a rushing attack that ranked 30th in the league this season (85.6 yards per game). The bruising QB is at his best when he scrambles, averaging 5.0 yards per carry throughout his career. He also ran for 12 touchdowns in just 23 games with the Denver Broncos.
With Tebow attacking defenses on draws and bootlegs and Maurice Jones-Drew finally healthy, the Jaguars would undoubtedly have one of the best ground games in the league.
In the passing game, Tebow wouldn't be a big improvement over Blaine Gabbert or Chad Henne. His throwing motion is still hideous, he telegraphs his passes and his career completion percentage is just 47.9.
But what he lacks in skills, Tebow almost makes up for in marketability. His jerseys are always some of the most popular in the league and he'd immediately bring national interest to a forgotten team.
Outside of that, don't expect Tebow to change much in Jacksonville.
